Nine manuscripts (Cambridge, St John's College A.17; Lincoln Cathedral 41, 82, 208; BL, Add 54231; Lambeth Palace 57; Westminster Abbey 17; Oxford, Bodleian, Lyell 11; and Salisbury Cathedral 127) contain a mark like a figure 2 with a long horizontal tail, transected by two vertical strokes. This mark is placed in front of the note of contents or ex libris inscription and appears to be peculiar to this house. The pressmark is illustrated by A. C. de la Mare, Catalogue of the Collection of Medieval Manuscripts Bequeathed to the Bodleian Library Oxford by James P. R. Lyell (Oxford, 1971), pl. 36a.
